Oscillator – tips on the patch!

November 15, 2011 | 8:43 am

Hey All. I made this oscillator in max. the plan is to run it inside a bpatcher. What do you think about it?

However, in this patch, I would like to adjust audio rate and lfo rate. So I need to figure out how adjust the frequencies of the oscillator so I can bring them from audio rate to LFO rate if need be.

Thanks for your help!
Argee.

here is an update on what I’ve done! I don’t know how many people have taken a look at this. Thanks to Chris Muir and Oli Larkin for helping to figure out the sine oscillator sync.

I’m still trying to figure out how to be able to adjust the rate from audio rate to LFO rate.

I’ve also attached a picture of what it looks like. I’m using some fpics, so i dunno if they’ll show up in the compressed copy/paste.

Part of the problem with running this at LFO rates is that there is some serious DC blocking code which makes tri~, saw~, et al not work at sub-audio rates.

Hrm…. Is that in this particular patch that I have some DC blocking code (what is dc blocking code?)? or just the objects themselves in general? I seem to have a working Multi-wave LFO here. Let me know if I'm delusional or whatever. I did stay up most of the night. :P

I've replaced my background with a panel object to make it a little easier on the eyes. I've also attached a screenshot of the LFO to get the overall effect.

The band-limited oscillators have dc-blocking on their output:
